Ashlee Simpson Parties With Her Girlfriends At LA Club — Was She Celebrating Her Impending Divorce? Exclusive!

Ashlee Simpson sure didn’t seem like someone going through a split the other night at SHG’s Eden night club in LA! She was laughing and drinking with her girlfriends!

Even though Ashlee Simpsonhas filed for divorce from her husband of three years, Pete Wentz, her relationship drama isn’t affecting her partying life! HollywoodLife.com has learned exclusively the 26-year-old singer went out with her girlfriends to SHG’s Eden night club in Los Angeles Friday Feb. 4. Was she celebrating her impending split?

“Ashlee came around 1:00 am with a group of girls,” an eyewitness tells us. “She was laughing and chatting outside on the patio. They were definitely having some sort of a girls’ night out.”

Our source adds, “It seemed like Ashlee didn’t have a care in the world. She was drinking sugar-free Redbull and Grey Goose vodka.”

Randomly, Mini Gaga and Mini Beyonce — two little people who dress up and sing hits like “Paparazzi” and “Telephone” — were performing at the new hot spot when Ashlee arrived. The club reportedly went wild as the mini duo performed the popular covers.

For someone going through a divorce, Ashlee was acting pretty cheerful. She and Pete, 31, got married in May 2008 and had shortly thereafter had their son, Bronx. Do you think she’s excited to be single again?
